Muskies spawning can get violent.

Here's a video of Muskies spawning in the canals at Okoboji. I missed the roughest part.  and look how beat up she is at the end.
Interesting how they went in circles head to vent.
I'm sure releasing eggs and semen and then it was all over and the big female left.
I always thought they swam side by side releasing but this tells me they stir the spawn themselves.
